Studies on relationship between crop growth and yield of sesame (Sesamum indicum L.) under different weather conditions

Abstract

An experiment was conducted on experimental farm Department of Agronomy, College of Agriculture, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani, during kharif season 2017, entitled “Studies on relationship between crop growth, yield and physical environment within the crop canopy of Sesame (Sesamum indicum L.) under different weather conditions”. An experiment was conducted in randomize block design with six replications. Treatment under study were four sowing dates in kharif season i.e. D1 (23rd MW), D2 (25th MW), D3 (27th MW) and D4 (29th MW), and one variety AKT-64. The results found that all the biometric observations (plant height, No. of leaves, No. of branches and dry matter, days to 50% flowering and days to capsule formation, yield contributing characters such as total number of capsules plant-1, seed yield (kg/ ha-1), straw yield (kg/ ha-1) and biological yield (kg/ ha-1),) were significantly highest yield in sown in D2 (25th MW) followed by D1 (23rd MW).Sowing at D2 (25th MW) found superior over the rest of treatments with production of highest grain yield (440.8 kg /ha-1) followed by sowing in first sowing date D1 (23rd MW) (386.3 kg/ ha-1), third sowing date D3 (27th MW) (317.8 kg/ ha-1) and lowest grain yield was observed in fourth sowing D4 (29th MW) (237.2 kg/ ha-1).
